BACKGROUND: One of the most, probable pathogenesis of vitiliga is autoimmune. Systemic cor tico st,eroids suppress immunity and may arrest the progression of vitiligo and lead to repigmentation. OBJECTIVE: We have assessed the clinical effect of a oral small oral dose of corticosteroid to minimize side effects in vitiligo patients. METHODS: Thirty four patients(9;male, 25;female) with vitiligo were evaluated in this study. The patients took 7.5mg-20mg prednisolone initially for 2 months and then the dosage was tapered to half of the initial dosiat the 3rd month and half of dose of 3rd month for the last 4th month. We compared the effcct of treatment of vitiligo before and aft.er the study by photographs. and side efferts were issessed at. 1, 2, 3 and 4 month. RESULTS: The arrest of the progression of vitiligo was noticed in 79% of patients and repigmentation was noticed in 59% of patients which is statistically significant. The effect, of treatment according to extent, duiation, type, and site of vitiligo were not statistically significant. The side effects of treatment were minimal and did not affect the course of treatment. CONCLUSION: Small doses of iral corticosteroids are effective without any significant side effects in preventing progression and loiiduce repigmentation of active spreading vitiligo and generalized type of vitiligo that is difficult to treat with topical corticosteroids.

Increased death rate resulted from cardiovascular disease called for the study on the autonomic nervous system and cardiovascular system. It is known that an HRV (heart rate variability) spectrum analysis based on ECG (electrocardiograph) signals could be used to define activity of sympathetic and parasympathetic nervous system noninvasively. However, it is important to prove whether suggested HRV analysis method could provide the useful information for observing autonomic nervous system quantitatively and objectively before clinical application. In this study, 14 rats were used and divided into two groups, sympathectomy group and vagotomy group, respectively. During the experiment, ECGs of rats were collected three times at each experimental condition. After the application of Berger's series algorithm to the ECG raw data, HRV spectrum was obtained via FFT (fast Fourier transform). Power contents for each frequency bands were calculated from HRV waveforms. Two peak values, HF (high frequency) and LF(low frequency), representing autonomic nervous system status were used to extract the parameter, HF/LF ratio. Results showed that HF/LF values were increased for the sympathectomy group and decreased for the vagotomy group. It implies that the variations in HF/LF components exhibits the information for the classification of ANS(autonomic nervous system) function quantitatively. HRV analysis algorithm developed from this study could be expanded for the observation of autonomic nervous system variations in human.

BACKGROUND: In the Republic of Korea, there had been no reports about indigenous malaria cases since 1984 until a vivax malaria case was detected in 1993. Thereafter fram 1993 to 1996, 486 malaria cases were reported. Most of the patients were soldiers in the northern militarized zone. However, since 1997, several patients with malaria were detected in Kang Hwa where there had previously been no report of malaria cases. It is our intent to report the 16 cases diagrnosed in Kang Hwa Community Hospital from January 1, 1997 to August 10, 1998. METHODS: Medical records of the malaria cases from January 1, 1997, to August 10, 1998 in Kang Hwa Community Haspital were reviewed. All of the patients had no histories of traveling abroad, drug abuse or blood transfusion. They were all civilians. Laboratory studies including blood cell count, routine chemistry and platelet-associated IgG(PAIgG) and abdominal sanography were taken. RESULTS: All of the patients were diagnosed with malaria by blood smears. Common symptams were fever(100%), headache(94%), rigors(81%), myaJgia(56%), nausea or vomiting(44%), alternate day fever (25%), left flank pain(19%), diarrhea(13%), and abdominal pain(13%). Splenomegaly was detected in 92% of cases by sonography. Laboratory findings included leukopenia(37.5%), anemia(37.5%) and thrombocytopenia(81.3%). Platelet-associated IgG was elevated in 1 of 5 thrombocytopenic patients who had had the laboratory study performed. All recovered withaut complications. CONCLUSIONS: Cases of indigenous malaria have been progressively increasing in the Republic of Korea. Fortunately, patients responded well to treatment, but continued interest will be required in the future.

OBJECTIVE: To identify the effects of isokinetic strengthening of trunk muscles on balance in hemiplegic patients after stroke. METHOD: All participants were ambulatory hemiplegic patients, injured at least 6 months prior to study. The patients (n=16) were randomly divided into two groups. The control group received neurodevelopmental treatments and gait training 3 times a week. In addition to the same treatments provided for the control group, the experimental group received trunk isokinetic strengthening exercises using isokinetic dynamometer 3 times a week. Trunk muscle peak torque and balance in the experimental group were compared with those in control group at baseline and 4 weeks after treatments. RESULTS: There were no significant differences in age, lesion of hemiplegia, time after stroke onset, trunk muscle strength and Berg balance score before treatments between two groups. In the experimental group, peak torques of trunk extensor increased significantly at 60degrees/sec and 90degrees/sec at 4 weeks (p<0.05), but there were no significant improvements in peak torques of trunk flexor at all degree and extensor peak torques at 120degrees/sec. Both the extensor and flexors showed no significant changes in the control groups. In the experimental group, a mean percent change in peak torque involving the trunk extensor was significantly increased at 60degrees/sec. In the experimental group, Berg balance scores, 10 m gait velocity, sit to stand and gait 3 m and return, and 10 seconds stair up and down were improved (p<0.05). No significant improvements were noted in the control group. CONCLUSION: Isokinetic strengthening of trunk muscles can improve balance in hemiplegic patients.

PURPOSE: To evaluate changes in clinical outcomes, inflammatory cytokine levels, and tear osmolarity in the tears of patients with moderate to severe dry eye syndrome before and after the application of topical 1% methylprednisolone. MATERIALS AND METHODS: Thirty-two patients with moderate to severe dry eye unresponsive to previous aqueous enhancement therapy were enrolled. Five patients were lost to follow up, and twenty-seven patients were eligible for analysis. Patients were instructed to apply topical 1% methylprednisolone four times per day, as well as to continue applying their current therapy of preservative-free 0.1% sodium hyaluronate four times per day. Corneal and conjunctival staining scores, tear film breakup time (TFBUT), Schirmer test, and tear osmolarity were assessed at baseline, 4 weeks, and 8 weeks. Tear samples were collected at every visit for cytokine analysis. RESULTS: Corneal and conjunctival staining scores and TFBUT showed significant improvement at 4 (p<0.001, <0.001, <0.001 respectively) and 8 (p<0.001, <0.001, <0.001 respectively) weeks. Tear osmolarity decreased significantly at 8 weeks (p=0.008). Interleukin (IL)-1beta, IL-8, and monocyte chemoattractant protein-1 were significantly decreased at 8 weeks compared with those at baseline (p=0.041, 0.001, 0.008 respectively). CONCLUSION: Short-term treatment with topical 1% methylprednisolone not only improved clinical outcomes, but also decreased tear osmolarity and cytokine levels. By measuring the changes in cytokine levels and tear osmolarity, we could objectively evaluate the anti-inflammatory effects of topical methylprednisolone applied in the treatment of patients with moderate to severe dry eye syndrome.

BACKGROUND: When patients return to the emergency department shortly after being seen, it is generally assumed that their initial evaluation or treatment was inadequate. But in other aspects many short term revisits may be unnecessary in the aspect of emergency care because it is known that substantial numbers of patients use emergency department for nonemergency problems. So we analysed the tendency and the cause of short term revisit patients, determined the rates and the associated demographic, clinical, disease variables as a tool of quality assurance. METHODS: We carried out a chart review of patients seen in the emergency department, who revisited within 72 hours, of Young Dong Severance Hospital retrospectively between January 1, 1998 and September 30, 1999 (period 2), and compared with result between April 1, 1990 and March 31, 1991 (period 1) respectively. RESULTS: In the period 1, the total revisits patients were 204/21,025(0.97%), in that period scheduled revisits were 15.2%, the unscheduled were 84.8%, and the frequent revisits (more than 3 times) were 6.4%. In the period 2, the total revisit patients were 4,722/72,802 (6.49%), in that period scheduled revisits were 86.3%, the unscheduled were 13.7%, and the frequent revisits were 24.8%. The most common cause of revisit during the period 2 is a drug addictor (31.2%) that frequently used the emergency room for seeking drug. CONCLUSIONS : The scheduled revisit patients for dressing, medication, re-evaluation were increased enormously, so the medical care of these patients might be a part of job that performed in emergency department. And if the health care system could support the adequate nursing care facility, the portion of avoidable revisits of emergency department can be decreased. We also found that the emergency department is an important points for the early identification and referral for the treatment of patients who revisited emergency room for seeking drug, and the analysis of physician related factor in revisits patients may be used as a tool of quality assurance in the emergency department.

The Os odontoideum is a rare congenital disorder which is due to non fusion of axis and odontoid process so that seperation of odontoid process occurs. It causes various neurological syndrome because of atlantoaxial dislocation due to bony defect. To our knowledge, this type of malformation in a narrow sense has been reported only three cases in the world literature, and there are no reports of this malformation in Korea. With reviewing some of literatures, We present a case of the Os odontoideum which was confirmed by operation.
